Beschreibung

Allgemeine Beschreibung

Neutral red (C.I. 50040) - for microscopy Certistain^®, is a dry staining dye that is used to prepare a staining solution, that makes target structures in hematological specimen materials evaluable for diagnostic purposes. Neutral red belongs to the group of azines. Neutral red can be used for several staining such as supravital staining of leukocytes .In histology for nuclear staining, fluorescence staining, polychrome staining or for counterstaining in Gram staining.
As an IVD product and CE registered, it can be used hassle-free in diagnostics and laboratory accreditations. For more details, please see instructions for use (IFU). The IFU can be downloaded from this webpage.
